    <p>I'm generating UIImages with a bit-bucket, creating them on the fly and swapping the UIImageView's image. Is there a way to edit the UIImageView's Image directly? (ie. change the color of a specific pixel, without removing the UIImage from the UIImageView, and get it to redraw.) </p> <p>Currently, I'm flushing the UIImage and using imageWithCGIImage to make a new one, and assigning it to the UIImageView. This works. Shows no MemLeaks. But on the iPhone (3Gs) after about 100 image replacements, CRASHES. Cache'n issue? The memory summation seems to be hitting the phone's limit if cache not releasing, however, Simulator does not show memory consumption with each image swap. Stays flatlined without leaks.</p> <p>Note: topologyImage array is the RGBA pixel-bucket. The REF variables are not released. Every attempt to do so, crashes next call. Without, Instruments reports no leaks.</p> <p>=========</p> <pre><code>CGColorSpaceRef colorSpaceRef=CGColorSpaceCreateDeviceRGB(); CGBitmapInfo bitmapInfo = kCGBitmapByteOrderDefault | kCGImageAlphaLast; CGColorRenderingIntent renderingIntent=kCGRenderingIntentDefault; CGDataProviderRef provider=CGDataProviderCreateWithData(NULL,topologyImage,(I*I*4),NULL); CGImageRef imageRef=CGImageCreate(I,I,8,4*8,4*I,colorSpaceRef,bitmapInfo,provider,NULL,false,renderingIntent); UIImage *img=[UIImage imageWithCGImage:imageRef]; if( IMG[NDXtopo].vw ) { [IMG[NDXtopo].vw setImage:img]; } else { IMG[NDXtopo].vw=[[UIImageView alloc] initWithImage:img]; [master.view addSubview:IMG[NDXtopo].vw]; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
